I'm curious if any of the assembled body has had any problem with the B&S Quantum series 675 6.75Hp. The valve seats popping out or valves, springs etc. More specifically the intake side.
I have a Tory-built model 070 chipper/vac/shredder. I was shredding some mulch yesterday as this years bagged batches is to many to large chunks. Making it difficult for the wife to walk on it in the garden. She has MS and arthritis, so I was shredding it and when the bag is removed the safety shuts off the engine. It was working at full speed and song when it stopped as I removed the bag and emptied it. and refilled the gas.
When I went to restart it it didn't want to start. So I cleaned the air filter,carb and started it. It would only work at about half speed and slowed up when I put the air filter back on. It ran only slower than normal. It chipped fine but at a slower rate.
When I removed the fliter on the side facing the carb and engine there was oil on it and some slight oil smoke is coming out.
Spraying carb cleaner, slows it down almost to a stop. It is making only normal sounds like it was brought home it is about two years old.
I haven't put the bore scope camera in the plug hole yet or done a compression test yet. As it is raining out, and I don't have room in the shop
I know if the vanes in the head and engine block are plugged and dirty it can cause the seats to pop out. The vanes are clean and have been washed once this operating season.
Any body have any suggestions or comments. The
questions section at the website for small engine repair isn't working. http://www.small-engines.com/index.html
And really hasn't been updated since 05 with these new B&S Engines.
My last B&S factory training class was in the late 70's early 80's and these new engines seem to be a whole different really cheaply built engines.
